MSI Z77A G45 Infinite boot loop.

Hello! I'm experiencing what seems to be a common issue with this motherboard where it will power on for about 5 seconds then reboot itself. The bios never flashes on the screen and I have tried my psu on another computer and that isn't the problem. My specs are-PC Power&Cooling Silencer Mk2 950wIntel i5 3570kMSI Z77A G45Corsair 1600 4x2gb of ram.

I couldn't find anything in the ways of solutions for this problem, so if anyone has any insight it would be greatly appreciated.

New problem, my computer is about 7 months old. Didnt touch anything just one day it started this boot cycle. I think im just going to have to rma it and just when it gets fixed never turn off my computer. This problem appears frequently in this motherboard it seems.

I have a Gigabyte H77 and have a wierd similar problem, though it's probably not the same problem. I have an i5-3470 and a geforce 650 ti. It has to do with my screen which is a crt 4/3. If I remove the splash screen in the setup, or press the setup button or press the boot choosing menu the computer won't start. But if I switch my screen off, then I can start the computer, or go to the setup and boot to anything and then switch the screen on (even in the setup). Anyways if I let the splash screen on I can boot with my crt (though it not even at the right size sigh...). I tried with a 4/3 lcd and same problem too. If I plug a 16/9 screen it's ok. I haven't flashed the bios because I'm scared of messing with Windows 8 and I'm not supposed to have support with the OEM version.

So yeah it's probably not the same problem at all but I hope it helps anyways.

Now that I think about it before that I recieved a defect motherboard (same model as previous post) that wouldn't start. The fans were starting for 1 or 2 seconds then stopping, then starting again and so on. I brought it to a local computer repair shop to tell me what was wrong adn they told me indeed it was the motherboard, so I had amazon replace the motherboard for me. Now the one I have has the bug I mentionned but I can work around it.

The motherboard doesn't have a led nor a buzz so it's hard to know what's happening but here's a tip : if you only plug the motherboard with no cpu no ram, and power it, the fans are supposed to always be on. If they stop then it's either a problem with the motherboard or a wrong contact with the pc case or a short circuit with something that hits it.
